This study was conducted to evaluate the cadmium contamination level in milk products containing cocoa (chocolate flavour milk products), and its dietary exposure in vulnerable consumers, i.e. children aged one to five years old, pregnant and lactating women (PLW) in Indonesia. A total of 78 samples of milk products, which were registered in the Indonesian National Agency of Drug and Food Control (NADFC) and distributed in the Indonesian market, were analysed using Atomic Absorption Spectrophotometry Graphite Furnace (AAS-GF). Milk powder for children aged one to five years, UHT liquid milk, and condensed milk meet the NADFC regulation No. 5 of 2018. However, 63% of chocolate flavour PLW milk powder had Cd levels that exceeded the NADFC (maximum 10 µg/kg). Chocolate flavour milk has a higher Cd level than non-chocolate flavour milk products. The highest value of Cd exposure was in children aged three to five years old who consumed chocolate flavour milk powder, with an average value of 0.095 and P95 value of 0.151 µg/kg BW/day. However, based on the P95 exposure value, the contribution of Cd exposure for this product was only 18.12 and 42.27% to the PTMIJECFA and TWI-EFSA values, therefore, it was not considered a risk of health problems. For PLW milk powder, although 63% of samples exceeded the NADFC regulation, the P95 value of Cd exposure was 1.41 and 3.29% to the PTMI and TWI value, therefore, it was also considered not to pose a risk of health problems.
